Entreletras.org is a digital newspaper where I regularly collaborate. In classic film noir, we have seen many times how villains send anonymous letters intended to scare, extort or threaten their victims. To hide their identity, the medium used is a set of letters cut from the press with different fonts and colors that make up an enigmatic message. I have allowed myself to use this technique for more positive purposes. My PopArte lyrics reproduce the beginning of the poem "Nanas de la onion" by Miguel Hernandez.
